Used as a crosslinking agent in the synthesis of functional polymers, particularly in the development of stimuli-responsive hydrogels and elastomers. Its terminal alkene groups allow for efficient post-polymerization modification via thiol-ene click chemistry or radical polymerization, enabling tailored network structures. Commonly employed in creating smart materials for drug delivery, soft robotics, and self-healing systems due to its ability to introduce flexible spacers and reactive sites within polymer matrices. Also utilized in liquid crystal formulations to adjust phase behavior and enhance alignment properties.
